1 Metal drums or jerricans with a minimum thickness of 0.82 mm body and 1.09 mm heads which are manufactured and marked prior to January 1, 1997 may be reused. Metal drums or jerricans manufactured and marked on or after January 1, 1997, and intended for reuse, must be constructed with a minimum thickness of 0.82 mm body and 1.11 mm heads.
Formula for Metric Units
Formula for U.S. Standard Units
where:
e1 = required equivalent wall thickness of the metal to be used (in mm or, for U.S. Standard units, use inches).
e0 = required minimum wall thickness for the reference steel (in mm or, for U.S. Standard units, use inches).
Rm1 = guaranteed minimum tensile strength of the metal to be used (in N/mm2 or for U.S. Standard units, use psi).
A1 = guaranteed minimum elongation (as a percentage) of the metal to be used on fracture under tensile stress (see paragraph (c)(1) of this section).
